IMPROVEMENT IN ELECTRO MAGNETIC SIGNAL-HOUSES.

Specication forming part oi Letters Patent N o. 121,870, dated December12, 1871.

To all whom t may concern:

Be it known that I, THOMAS S. HALL, of West Meriden, in the county ofNew Haven and State of Connecticut, have invented a new and usefulImprovem ent in Electro-Magnetic Si gn al-Houses; and I do herebydeclare the following to be a full, clear, and exact descriptionthereof, which will enable those skilled in the art to make and use thesame, reference being had to the accompanying drawing forming part ofthis specification, in Which drawing- Figure 1 is an elevation of thisimprovement. Fig. 2 is a vertical section taken in the line .s .fr ofFig. 1. Fig. 3 is a horizontal section in the line y y of Fig. 2.

Similar letters indicate corresponding parts.

This invention relates to electro-magnetic sig I nal and battery-housesfor railroads; and consists in combining, with the battery-chamber, twoor more air or non-conducting chambers Which surround such chamber 011all sides for the purpose of protecting the battery from frost. Itconsists also in inclosing the signals on all sides so that they cannotbe tampered with, the signal-cupola being provided with glass faces onthe front and back to allow them to be seen When they have been broughtinto proper position, While, at the same time, the signal mechanism iseffectually protected against the weather.

A designates an electro-magnetic railroad signal and battery-house,provided with a cupola, K, for containing and exhbiting a signal. Saidhouse contains a central chamber, B, provided with a series of shelves,C, Whereon the batteries of the electro-magnetic apparatus are to beplaced.

The central battery-chamber is surrounded by a series of two or moreseparate air-chambers for the purpose of protecting the batteries in thecentral chamber from frost. In this example the series of air-chambers,except at top and at the door-Ways, are three in number, marked,respectively, D E F. The air-chambers are made close and tight by anysuitable material, such as felt or paper. C is a door-way to obtainaccess to the battery-chal'nber, and the door-Way is provided With anouter door, H, and an inner door, I, the latter being a double door, containing an air-chamber, J. The outer door can be made double also, or anadditional door may be provided. The cupola K rises from the top of thehouse, and contains the signal which is operated by the electromagneticapparatus. It is inclosed so as to prevent the signal contained thereinfrom being tampered with, and is provided with glass faces L L on thefront and rear, opposite the place occupied by the signal when inaction; at the same time the cupola serves to protect the signalmechanism against the influence of the Weather.

What I claim as new, and desire to secure by Letters Patent, is-

The railroad electro-magnetic signal and battery-house provided with twoor more non-conducting chambers or spaces surrounding thebattery-chamber and an inclosed signal-cupola, substantially asdescribed.
